Martin kept track of the number of times he had to flip a coin before it landed tails up.
number of flips to land tails up
which is a true statement about the dot plot?
six times it took 4 flips of the coin to land tails up.
twice it took 4 flips of the coin to land tails up.
it took 6 flips of the coin to land tails up more often than any other number of flips.
the roatact number of flins it took to land tails un was 6.

First locate the turning point (vertex) of the graph. which is at the coordinates x=5 and y=9 or (5; 9).to determine whether it's a maximum or mininum value, you have to discern whether the vertex's y-value is the highest value or lowest value the graph can reach. since the vertex's y-value, 9 is the highest value the graph can reach, it will be a maximum.another basic way to determine whether the vertex's value is max or min is to see if the graph is smiling or sad. if it's smiling, the turning point/vertex would be a minimum, while a sad parabola would have a maximum y-value at the vertex.
